Burning trash on the farm

Our operation on the farm generates a lot of burnable trash, more than our dumpster can handle some of the time. So we just burn it on a pile. We need to come up with a better, safer way to handle this burnable waste. How do you safely burn your trash on the farm? There are large incinerators out there but very costly. Open burning is alowed here but during dry weather, a ban sometimes is placed. A lot of old pallets and cardboard are burned. Any ideas?
